Abstract
The relative size of polyribosomes showing [beta]-gal-actosidase activity has been measured for over 20 strains of E. coli. Organisms which have deletions in the acetylase-permease part of the lactose region have smaller polysomes than the wild type. Some point mutations, including amber mutants, also have smaller polysomes. Wild-type revertants of these mutants have the larger wild-type polysomes. It is concluded that the messenger RNA for [beta]-galactoside induction is polycistronic during the translation process as well as in transcription, and contains information for making [beta]-galactosidase as well as the other proteins of the lactose region.This publication has 14 references indexed in Scilit:
